  • Systems and methods for variable steering assist-II
    Patent number: 9969426
    Abstract: Methods and apparatus are provided for controlling a steering assist unit of a vehicle. The method includes receiving first accelerometer data, second accelerometer data, and third accelerometer data then comparing and calculating differences between the first accelerometer data, second accelerometer data and the third accelerometer data to determine a relative movement values for the second and third locations. The relative movement value represents the contraction or expansion of separate systems as they independently move at or near the second and third locations. The method further includes outputting a control signal to control the travel of the steering assist unit based on the relative movement values.
    Type: Grant
    Filed: June 1, 2016
    Date of Patent: May 15, 2018
    Assignee: GM Global Technology Operations LLC

  • Systems and methods for variable steering assist
    Patent number: 9085317
    Abstract: Methods and apparatus are provided for controlling a steering assist unit of a vehicle. The method includes receiving sensor data indicating a wheel position of a wheel relative to a frame of the vehicle, and determining a travel limit value for the steering assist unit based at least on the wheel position of the wheel. The method further includes outputting a control signal to control the travel of the steering assist unit based on the travel limit value.
